Tractography based on non-invasive diffusion imaging is central to the study of human brain
connectivity. To date, the approach has not been systematically validated in ground truth …

This paper proposes and tests a technique for imaging orientationally invariant indices of
axon diameter and density in white matter using diffusion magnetic resonance imaging. Such …
